Which Is The Smallest DNA?

Is DNA smaller than a molecule?

DNA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wide.

Each nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base..

How much DNA is in a chromosome?

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

What Colour is DNA?

Figure 2: The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue).

What is the shape of DNA called?

double helixThe double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a “double helix,” in the journal Nature.

Which is smaller gene or DNA?

Genes are the smallest. DNA contains the genes, the reading material which are made from nucleotides. Chromosomes contain the DNA.

Which is the smallest virus?

The smallest animal viruses belong to the families Parvoviridae and Picornaviridae and measure about 20 nm and about 30 nm in diameter, respectively.

What is the largest virus in the world?

MimivirusMimivirus is the largest and most complex virus known.

Which animal is smallest in the world?

The Kitti’s hog-nosed bat is the world’s smallest mammal at 1.1 inches. Averaging between 1.1-1.3 inches (2.8-3.3 centimeters) with head and body combined, the Kitti’s hog-nosed bat, or Craseonycteris thonglongyai, is the world’s smallest mammal.

Is DNA bigger than a chromosome?

To store this important material, DNA molecules are tightly packed around proteins called histones to make structures called chromosomes. … The largest chromosome, chromosome 1, contains about 8000 genes. The smallest chromosome, chromosome 21, contains about 300 genes.

Is gene or DNA bigger?

A gene produce a specific product, usually a protein, or an enzyme that are used for specific action. The DNA molecules contains thousands of genes which is located inside chromosomes. Therefore, gene is smaller than DNA.

What is the simplest virus?

The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins. The most complex can encode 100 – 200 proteins.

What is the biggest part of DNA?

Chromosome 1 is the largest human chromosome with approximately 220 million base pairs, and would be 85 mm long if straightened. DNA does not usually exist as a single strand, but instead as a pair of strands that are held tightly together. These two long strands coil around each other, in the shape of a double helix.

Where is gene located?

Genes are found on tiny spaghetti-like structures called chromosomes (say: KRO-moh-somes). And chromosomes are found inside cells. Your body is made of billions of cells.

What is inside DNA?

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). … To fit inside cells, DNA is coiled tightly to form structures we call chromosomes.
